Motion problems when HD movie not viewed at full size in Youtube (1 post)

    Forgive the second post… I have been doing some more troubleshooting and thought I’d cracked my problem…

    Does anyone else get occasional lines during motion (not interlacing) and motion jerks with their HD video when it is viewed in anything other than Full Size HD?

    My original footage was shot on an HD JVC Camera 1920 x 1080/50p AVCHD. Final Cut Pro converts it to 29.97 Apple ProRes 422 with Field Dominance: Upper (Odd).

    I found that I saw a lot of jumpyness before seting the data rate at 15000 kbps in MPEG Streamclip. Deinterlacing was set to on, Faststart on etc. There is still slight “lag” on panning shots, but watching the converted file on my computer and in Full HD on youtube (at full size) it is acceptable.

    Is this a problem with youtube or with my conversion process? I have heard that AVCHD cameras have caused similar problems for others. Has anyone found a solution?

    Thanks,
